this seems to work but all the recordings are zero length with no audio in them! have tried recording for short and long times...no difference.

Hi!

When you opened a recording from the home screen or a collection, at first sight the recording is zero-length and it will not be played automatically. After opening you have to play them too. Just select Play button (selected by default) on the bottom of the screen and hit the middle button of the 5-way pad to start playing.

I developed and tested this .ini on a Kindle 3 3G EU (v3.2.1+JB+LP) and it works for me.

It worked for thomass too.
I think it should work for you too. Just try again.
